Description

[Detailed description of the invention] [Industrial application field] The invention can be used, for example, in wardrobes, wardrobes,
The present invention relates to a mounting bracket for an opening/closing plate-shaped body such as an opening/closing door provided in an opening of storage furniture such as a cupboard or a decorative mirror as large as a person.

[Conventional technology]

As a conventional opening/closing plate-shaped body mounting bracket, for example, as shown in Japanese Patent Application Laid-open No. 56-156375, a door plate is connected to storage furniture via a parallel link, and once pulled out toward the front. There has been known a structure in which the device is slid laterally along the surface of the opening.

In the conventional type mentioned above, the door plate moves away from the opening toward the front and then moves laterally, so the opening can be opened wider than with a simple sliding door type door plate.
In addition, compared to a simple swing-opening type, it is convenient in that it is easy to open and close in places where there is not enough space on the front side of the door, but it does not allow for large numbers of storage furniture with the same specifications to be placed side by side. In some cases, the door could not be opened due to contact with an adjacent door.

Therefore, as an opening/closing plate mounting bracket that can avoid the interference between the opening/closing plate bodies as described above, the applicant of the present invention has developed a device having the following configuration [ ] as shown in FIGS. 13 and 14. was developed and filed first (Utility Application No. 191972, 1983).

[] Mounting frame 1 attached to furniture, etc.
A slidably extendable support frame 3 having a mounting surface for the opening/closing plate-like body 2 is attached so that it can be freely switched between a stored position and a drawn-out position by swinging within a certain angle range with one longitudinal end of the support frame 3 as a fulcrum. In addition, spring balls or the like are installed between the slide frame parts 3A, 3B, and 3C of the support frame 3 to elastically lock and hold these slide frame parts 3A, 3B, and 3C at the maximum storage position and the maximum extension position, respectively. A detent mechanism 50 is provided between the mounting frame 1 and a member 51 connected to the support frame 3, and a plate spring or the like is provided between the mounting frame 1 and a member 51 connected to the support frame 3. An opening/closing plate-like body mounting bracket provided with a detent mechanism 52.

In the device using the opening/closing plate-like mounting bracket of the prior application mentioned above, the opening/closing plate-like body is swung open in an inclined position with respect to the opening of the furniture, and the support frame 3 is moved along the direction of the inclination. Since it is telescopically operated, it is useful in avoiding interference between opening and closing plate-like bodies at adjacent positions, as in the prior art described above.
Maintaining the open and retracted postures of the opening/closing plate-like body is
Since this is performed by the detent mechanisms 50 and 52, there are the following problems. That is, the detent mechanisms 50 and 52 operate when an operating force of a certain level or more is applied to the support frame 3 in the swing direction and slide extension/contraction direction.
The support frame 3 is configured to allow rocking and sliding movement, and when the swing operation position and the slide extension/contraction operation position of the support frame 3 are between the two positions, the detent mechanisms 50 and 52 hold the position. The structure is such that it does not work at all. Therefore, when the plate-like body 2 is in the closed state, if an external force of a certain level or more is applied to the plate-like body 2 in the sliding extension direction of the support frame 3, the plate-like body 2 will unexpectedly open and move. There is a problem of collision and damage to other plate-shaped bodies adjacent to the plate. Moreover, even in the state where the plate-shaped body 2 is opened,
When an external force of more than a certain level acts on this plate-like body 2 in the retracting direction around the swing fulcrum of the support frame 3, the plate-like body 2 unexpectedly swings and collides with other adjacent plate-like bodies, resulting in damage. There is a problem.

[The problem that the idea aims to solve]

This invention allows the opening to be opened wide without interference between the opening and closing plates even when a large number of storage furniture are arranged side by side, and in cases where there is not a very large space on the open side of the opening and closing plates. too,
To obtain an opening/closing plate-like body mounting bracket for storage furniture that allows the opening/closing plate-like body to be fully opened with easy operation, and to ensure that the posture of the opening/closing plate-like body is maintained in the stored position and the open position. That is its purpose.

[Means to solve the problem]

The technical means of the present invention for achieving the above object is a mounting bracket for an opening/closing plate-like body that can freely open and close an opening of storage furniture. One end of the support frame is connected to the plate-shaped body, and the other end of the support frame is pivotally connected to the plate-shaped body, so that both the support frame and the opening/closing plate-shaped body can swing freely within a certain angular range around the vertical axis of the pivotally connected position. It is installed on.

[B] The support frame is configured to be expandable and contractible by relative sliding of a plurality of rail members,
The opening/closing plate-like body connected to the other end of the support frame is kept in an open state facing the opening of the storage furniture in an inclined position, and is moved to the pivot connection position on the mounting frame side. It is attached so that it can slide freely in the far and near directions.

[C] Between the mounting frame or a member attached thereto, or both, and the support frame or the opening/closing plate-like body, or both,
angle setting means for defining a maximum swing angle of the support frame with respect to the mounting frame; and angle setting means for preventing the extension operation of the support frame when the opening/closing plate body is in a storage position that closes an opening of the storage furniture. 1. When the stopper mechanism and the opening/closing plate are in an open position where the opening/closing plate body is swung toward the side facing the opening in an inclined position, and the supporting frame is in the extended state, the support frame and the opening/closing plate are A second stopper mechanism is provided to prevent the shaped body from swinging toward the storage position.

[d] The first stopper mechanism is configured by a combination of a first member attached to the opening/closing plate side and a second member attached to the storage furniture side, and both of these members are , as the opening/closing plate-shaped bodies are opened/closed and swung, the opening/closing plate-shaped bodies are brought into contact with each other and maintained in an engaged state at the retracted position, and the open position is arranged at a position where the engagement is released. Further, one of the two members is provided with an abutment portion 8 that restricts movement of the support frame in the extension direction when engaged in the storage position.

[E] The second stopper mechanism is oscillated as the support frame slides in the extension direction, and is positioned in a tensioned position between the mounting frame and the support frame or the opening/closing plate-like body. It is comprised of a swinging member elastically biased in this way, and a release operation means that changes the attitude of the swinging member toward the tension release side as the support frame is retracted.

It has the configurations described in [A] to [E] above.

[Effect]

The effects of taking the above technical measures are as follows.

Due to the configurations [A] and [B] above, the opening/closing plate-like body can swing around one pivot connection point on the mounting frame side and can slide while facing the opening in an inclined position. Therefore, not only is the pivot structure of the door simple, but it can also be used in places where a large number of storage furniture equipped with such opening/closing plate bodies are placed close together, while avoiding interference with the opening/closing plate bodies. Can be opened and closed successfully.

From the configurations [C] to [E] above, when the opening/closing plate is in the closed state, even if an external force is applied to the opening/closing plate in the sliding extension direction of the support frame, the opening/closing plate will not move. An unexpected opening movement of the support frame can be reliably prevented by the abutting engagement of the first stopper mechanism, and an external force in the retracting direction around the swinging fulcrum of the support frame acts on this opening/closing plate. Also, the rocking of the plate-like body can be reliably prevented by the tensioning action of the second stopper mechanism.

Further, from the configurations [C] to [E] above, switching between the stopper action state and the stopper release state of both the stopper mechanisms is performed using essential operations such as rocking of the support frame and sliding extension and contraction. Therefore, the opening/closing plate-like body 2 does not require any operations other than the original opening/closing operations, and can be performed quickly and easily.

[Effect of idea]

Based on the effects of ~ above, in order to avoid interference between the opening and closing plates when a large number of storage furniture are placed side by side in a place where there is not enough space in front of the opening, it is possible to Although it is possible to slide in an open state with the bodies facing each other in a tilted position, it is also possible to maintain each posture reliably in the open state in the tilted position and the retracted state with the opening closed. effective.
